Want to run a modified ECU or software reflash? Good luck in California.
I'm wondering how this will effect cars with deleted EGRs and tunes....... Any thoughts?
its just adding some un-needed hassle and stress, its funny the TDI's are more efficient tuned. Hopefully it doesn't make smog more exepsniveI too don't disagree with everything said above, and am too young to have witnessed how bad smog used to be Los Angeles. It's interesting though when I first purchased my TDI that it didn't even require a smog check, then a few years later I have to. The car has been passing just fine, though now this can come as another hurdle that might have to be passed if I ever run into any issues.........
For people that need to jump over it, I've been reading they just simply retune the car back to OEM stock, and put whatever parts needed back on. I was also thinking they can swap ECUs, but then there is the hassle of needing the instrument cluster and immobilizer that need to be installed as well, which sounds like more work then just getting it retuned.
It sure is becoming more difficult to own a modified car that wasn't manufactured before '76 here. I'm not about to even get into classic cars with how the market for them has been - it's insane.
Sounds like they need a spare ecu with immo delete.For people that need to jump over it, I've been reading they just simply retune the car back to OEM stock, and put whatever parts needed back on.

I just used VCDS in the "OBD II" mode (when you first start the application, you have buttons labeled "Select", "OBD-II", "Applications", "Settings", "Auto Scan" etc. "Select" is what you normally use to select the individual control module in the factory protocol, OBD-II button is what you use to see the generic/standardized OBD information that any generic OBD-II scan tool can do--and is the standardized protocol used during smog checks). Once the page loads/connection has been established, click "Mode 9" and it will display the CAL-ID (which, again, is your engine computer's part number and software version number) and CVN (checksum).Over the past year, the Bureau of Automotive Repair (BAR) has been extensively studying Cal ID and CVN and working with the California Air Resources Board (ARB), vehicle manufacturers, Smog Check industry representatives, and BAR Advisory Group members to gather input and develop an implementation plan. In accordance with California Code of Regulations, title 16, section 3340.42.2(c)(8), beginning July 2020, BAR will implement Cal ID and CVN checks for most model-year 2000 and newer vehicles as part of the On-Board Diagnostic Smog Check inspection failure criteria. Owners of vehicles identified with unapproved programming modifications will need to restore the computer to either stock or ARB-approved software in order to pass a Smog Check inspection.
I'm going for my semiannual emissions test on my 2001 Golf with stage 4 Malone tune and dynamic egr. I believe I'll pass like I always do because I've passed last 4 smog tests with same equipment. I'll update here in another month after I pass.OK,
I just smogged a 2002 NB with a stage 1 Upsolute tune. All smog equipment intact. I passed with flying colors. For the ALH equipped cars CARB is bluffing when they say they can detect a tuned car via the OBD II port. I am not saying it is not possible but it is not implemented. I think CARB is concentrating on more numerous models particularly pickup trucks. Some of the tunes and hardware alterations on pickups are a no brainer to find when they roll through the test station. Altered, unapproved, or missing emission equipment is an easy score for CARB and that is still their main focus.
It would be interesting to hear from PD and CR owners with stock hardware and mild tunes to see if they have the same experience.
good to hear Matt I just emailed you in regards to taking my 2001 in for test next week.OK, so I was doing a little homework on this subject last night. I will be making a more in-depth post.
Basically, what this boils down to is CARB/smog stations are using "Mode 9" to see the engine computer part number and software version number (which will make up the 'CAL-ID' portion of this check) and there is a checksum, which is referred to as a CVN (acronym for Calibration Verification Number).
I actually have a list of VW engine computers, gas and diesel, from 2005 through 2010, what each of their CAL-ID and corresponding CVNs are supposed to be. I then also found later that VW actually has a website where you can look this up yourself, it will also include the vehicle "Test Group", which you can see displayed on the 'Catalyst' sticker under the hood of your car. On Mk4s, it's supposed to be on top of the radiator core support.
The Volkswagen CVN info is found here.
You will notice that it only goes as far back as model year 2005 for most cars. So, this tuned ECU detection WILL NOT APPLY to ALH cars. And, apparently won't apply to 2004 BEWs, BHWs or BKWs (my Touareg V10 being an example--though mine is stock so not a concern at all).
Now, I have heard that some tuners can spoof the CVN. I would need to get my hands on a tuned 2005 or newer car to verify this for people using VCDS. I will also add, I have noticed that Rocketchip and sometimes TDTuning like to change the engine computer part number and software version number to give it its own identification, that might show up as a non-existent CAL-ID, giving away that it's a tuned ECU, even if the CVN is correct. So, Rocketchip owners beware (at least for cars 2005 MY and newer--once again, it appears ALH guys have nothing to worry about).
I will also add that there are CAL-ID and CVNs for automatic transmission computers as well. So those with DSG tunes may also want to double check that the CAL-ID and CVN matches in Mode 9 data on top of checking the engine computer, if you have VCDS, it does have a generic OBD2 feature where this should be able to be displayed.
If you have a CAL-ID and CVN that don't match, get ahold of your tuner and see what they can do.
Coming soon will be a more comprehensive post detailing step by step on how to check this out yourself using VCDS, with screenshots and all.
“This could take a while” showed up initially on our ‘03 (Malone tuned) wagon too. But after a few mins it popped up:Matt,
I dragged the VCDS out and under MOD 9 I found this:
CAL ID: 038906012FF 4104 (ADDRESS 0A)
TYPE 06 This may take a while... (after 30 minutes I think it wasn't happening at all, closed out VCDS)
